Degradable PEGs

NOF has developed novel degradable PEGs that have enzyme cleavable peptide linkers. 
Degradable PEGs have the same blood circulation time as non-degradable PEGs and are removed from the body faster than non-degradable PEGs, because they are cleaved to lower molecular weight PEG in cell.
